Washington’s color starts on the eastern crest of the Cascades and reaches the lowlands about a month later.
Larch and aspen around Washington Pass, Slate Peak and the Okanogan highlands turn in the second week of October;
the North Cascades, Picture Lake and the Rainier meadows follow in the middle of the month;
the lowland maples and cottonwoods of Puget Sound, the Gorge and the San Juans finish at the end of October and into early November.
Western larch, a deciduous conifer, is what gives the east side its yellow.
